A pronoun is a word that can take the place of a noun. Based on different form and function in the sentence, pronouns fall into several major categories such as personal pronouns, compound personal pronouns (reflexive), possessive pronouns, relative and interrogative pronouns, demonstrative pronouns, and indefinite pronouns.

This, that, these, and those can be used as demonstrative pronouns.

This and these are used when talking about one or more things that are nearby.

That and those are used when talking about one or more things that are far away.
